PULLULAN

PULLULAN: A skin protector

EXCIPIENT ⎪ FILM-FORMING AGENT 

What is Pullulan?

Pullulan is a natural polysaccharide obtained by the fermentation of starch by a strain of fungus called Aureobasidium pullulans. It is widely used in the cosmetic industry for its film-forming properties and its moisturizing and protective effects. Thanks to its ability to form a film on the skin, it is often used in masks, serums and anti-aging treatments to create an instant tightening effect. By forming a protective barrier, pullulan helps retain hydration and protect the skin from external aggressions. Not only does it improve the texture of skincare products, but it also acts as a natural stabilizer and binder, allowing better cohesion of ingredients.

Pullulan is a natural polysaccharide derived from plant starch by fermentation. In our Happy Cycles Body Serum, pullulan is used for its film-forming properties, forming a protective film on the skin to preserve its hydration and improve its appearance. It is also a fixing agent which promotes the cohesion of the different ingredients of the formulation.

Where does Pullulan come from?

Pullulan is produced by the fermentation of starch using a specific yeast, Aureobasidium pullulans, which breaks down starch into long chains of polysaccharides. This natural process creates a pure and non-toxic substance, commonly used in cosmetics and food products. In cosmetics, it is appreciated for its non-irritating properties and its compatibility with all skin types. The use of pullulan in care is increasingly common due to its many benefits, particularly for its moisturizing effects and its ability to form a thin protective layer, thus strengthening natural and organic formulations.

Properties and active ingredients

Pullulan has several beneficial properties for the skin, and it is known for its versatility in cosmetic products. Here are its main characteristics and actions:

1. Film-forming effect : Pullulan forms an invisible film on the skin, providing an immediate tightening effect which smoothes features and refines skin texture.
2. Long-lasting hydration : By creating a protective barrier, it helps retain moisture, making it an excellent moisturizer for dry and dehydrated skin.
3. Protection against external attacks : The film it creates protects the skin against pollutants and other environmental stressors, reducing the risk of irritation and sensitivities.
4. Stabilization and improvement of product texture : As a binding agent, it helps stabilize formulations and improves the texture of products, making their application more fluid and pleasant.
5. Antioxidant action : Although mild, this property helps protect the skin against free radicals, which is particularly useful in anti-aging products.

What are the benefits of pullulan?

Pullulan offers many benefits for the skin, thanks to its moisturizing, protective and smoothing properties. Here are the main benefits of this natural and versatile ingredient:

1. Immediate tightening and lifting effect : By forming a film on the skin, it creates a visible tightening effect which helps to smooth fine lines and wrinkles, for a more youthful and radiant appearance.
2. Hydration and moisture retention : It maintains hydration by forming a protective barrier, ideal for dry skin, by reducing transepidermal water loss.
3. Protection against pollution and impurities : The protective film acts as a shield that prevents pollutants from penetrating the skin, thus preserving its radiance and health.
4. Evening out skin texture : Thanks to its film-forming properties, it helps smooth the skin's texture, contributing to softer skin and a more even complexion.
5. Stabilization of cosmetic products : By improving the cohesion of ingredients, it makes formulations more stable and extends their lifespan, while facilitating application to the skin.

How to consume Pullulan?

Pullulan is primarily used topically in skin care and makeup products. Here are the main ways to benefit from this ingredient:

• Face masks : Used in peel-off masks and sheet masks, it helps create an instant tightening effect and leaves the skin soft and hydrated.
• Anti-aging serums and creams : Added to serums and creams, it smoothes fine lines and improves skin texture, contributing to a lifting effect.
• Protective mists : In facial mists, pullulan acts as a barrier against pollutants and hydrates the skin throughout the day.
• Makeup products : Integrated into makeup bases and primers, it offers a smooth and uniform finish, facilitating the application of makeup and prolonging its hold.
• Eye care : When applied under the eyes, it helps reduce the appearance of bags and fine lines, providing a refreshing and smoothing effect.

Note : Pullulan is generally well tolerated by all skin types, even sensitive skin. However, a skin test is recommended for reactive skin. It is stable in formulations and can be used daily without risk of irritation.

Any side effects?

Pullulan is generally well tolerated, but some side effects can occur, although rare:

1. Allergic reactions : Although very rare, an allergic reaction may occur. Symptoms include redness, itching or rash. If you experience a reaction, stop use and consult a healthcare professional.
2. Mild skin sensitivity : Some very sensitive skin may feel a slight feeling of tightness due to the film-forming effect. It is recommended to moisturize the skin after use if necessary.
3. Mild skin occlusion : On very oily skin, the protective film can cause a feeling of occlusion. In this case, it is advisable to use light formulations containing pullulan.
4. Buildup on the skin : With excessive use, pullulan may leave a slight residue. It is therefore recommended not to overdose on products containing this ingredient.
5. Temporary tightening effect : The tightening effect is temporary and should not be confused with a permanent solution for wrinkles or loss of elasticity. Pullulan is ideal for cosmetic use and instant effect.
